IMPROVEMENT IN ADJUSTABLE POLE EOE UARRIAGES,

'iU ALL WHOM IT MAY CONCERN:

Be it known that I, J.v E. PRUDDEN, of Birmingham, in the county of NewHaven, and State of Connecticut, have invented anew ImprovementinAdjustable Pole for Carriages; and I do hereby declare the following,when taken in connection with the accompanying drawings and the lettersof reference marked thereon, to be a full, clear, and exact descriptionof the same, and which said drawings constitute part of thisspecification, and represent, in-

Figur 1, a top view.

Figure 2, a front view; and in Figure 3, a section on line o a.

This invention is designed to make a carriage pole adjustable, so thatit maybe attached to different carriages, the couplings in which are atdifl'erent distances; and consists in the peculiar manner of attachingthe shackle to the cross-bar of the pole so that the shackles may be setat different distances from each other, as occasion may require.

To enable others to construct and use my improvement, I will proceed todescribe the same as illustrated in the accompanying drawings.

A is the shackle, formed with a socket, B, to fit the coupling on theaxle, C the cross-bar ot the pole, upon the under side of' which isformed a recess, D, and below the said recess a plate, E, is attached tothe cross-hm, and the shackle A formed so as to be placed on over theplate E, as seen in fig. 3. One edge of the plate E is inclined as at a,and through the shackle A a key-bolt, F, is placed, having its headinclined to correspond to the inclinc'on the plate E, so thatby turningthe nut G on to the bolt F, the inclined part of the bolt F draws downfirmly against and upon the incline upon the plate E, and secures theshackle in that position.

When it is desired to adjust the pole, loose the nut G and move theshackle on the plate E along the recess l), and, when in the requiredposition, turn the nut G hard down, and secure the shackle in thatposition.

I do not broadly claim an adjustable carriage pole, but, having thusfully described my invention, what I do claim as new and useful, anddesire to secure by Letters Patent, is

The combination of the key-bolt F, the inclined plate E, and the shackleA, when constructed and arranged so as to he adjustable, substantiallyin the manner specified.
